MOSFET yaba yuzuye cyangwa kimwe cya kabiri iragenzurwa?

MOSFETs (Metal-Oxide-Semiconductor Field-Effect Transistor) ikunze gufatwa nkibikoresho bigenzurwa byuzuye. Ni ukubera ko leta ikora (kuri cyangwa kuzimya) ya MOSFET igenzurwa rwose na voltage yumuryango (Vgs) kandi ntibiterwa numuyoboro fatizo nkuko bimeze kuri transistor ya bipolar (BJT).

Muri MOSFET, voltage yumuryango Vgs igena niba umuyoboro uyobora wakozwe hagati yisoko n'amazi, kimwe n'ubugari n'umuyoboro w'umuyoboro uyobora. Iyo Vgs irenze igipimo cya voltage Vt, umuyoboro uyobora urakorwa kandi MOSFET yinjira kuri leta; iyo Vgs iguye munsi ya Vt, umuyoboro uyobora urazimira kandi MOSFET iri murwego rwo guca. Igenzura riragenzurwa rwose kuko voltage yumuryango irashobora kwigenga kandi neza kugenzura imikorere ya MOSFET idashingiye kubindi bipimo cyangwa voltage.

Ibinyuranyo, imikorere yimikorere igenzurwa nigice (urugero, thyristors) ntabwo ihindurwa gusa nigenzura ryumubyigano cyangwa amashanyarazi, ariko nanone nibindi bintu (urugero, voltage ya anode, amashanyarazi, nibindi). Nkigisubizo, ibikoresho bigenzurwa byuzuye (urugero, MOSFETs) mubisanzwe bitanga imikorere myiza muburyo bwo kugenzura neza no guhinduka.

Ese MOSFET yuzuye cyangwa igice cyagenzuwe (2)

Muri make, MOSFETs igenzurwa byuzuye ibikoresho bikora bigenzurwa rwose na voltage yumuryango, kandi bifite ibyiza byo gusobanuka neza, guhinduka cyane no gukoresha ingufu nke.
